Yes, the refs got it right. 43 was in front, Liberty receiver was fighting for it, even as they were falling to the ground. When they hit the ground, 43 secured it, Liberty receiver rolled over on top and tried to wrestle the ball away. Possession 43, 1st down on the 20. End of "controversy". Blocked pass on the final play was not even close to being PI, either, so don't go there, next.
And, for the love of all humanity,, someone move that guy with his stupid cow bell. It is clearly a breech of the rules to be clanging that stupid thing while the opposing team is at the line and starting to run the play.
